SPECIFICATION forming part of Letters Patent No. 294,986, dated March11, 1884. Application filed September 4, 1883. (No model.)

1' b ctZZ whom it may concern:

Be it known that we, D. A. O. FUNDER- BURK and JEFFERSON L. FUNDERBURK,citi- Zens of the United States of America, residing at Bainbridge, inthe county of Decatur, in the State of Georgia, have invented a new anduseful Improvement in Plows, of which the following is a specification.I

Our invention relates to improvements in plows; and the objects are,first, to provide means by which the mold-board of the plow is preventedfrom displacement in any direction; second, to provide improved meansfor adj usting the handles to any desired position and, third, toprovide an improved check-bolt for the 'clevis to rest against, wherebythe run of the plow may be controlled as to depth; fourth, to provide animproved removable and adj ustable side frame or loop and an adjustablelandside, as hereinafter more fully stated.

Our invention consists in the novel construc tion and combination ofparts, as will be hereinafter more fully set forth, and specificallypointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a plowhaving our improvements attached. Fig. 2 is a View of the adjust-ablestirrup and handle braces. Fig. 3 is a view of the lower end of the beamand side frame, with shoulder-cuff and bolt and mold board bolt inposition; and Fig 4 is a view of the cuff and bolt and washer.

The letter A represents the beam of the plow, formed or provided withthe requisite bolt-holes at the land end, substantially as shown, forthe purpose of admitting the passage of the bolts wherewith the landsideand side stirrup are secured in place. In the draft end of the beam isformed the vertical slota, and fitted therein is the bolt b, havingproper head, and provided on the freecnd with screwthreads to receivethe nut c. This bolt and nut clamp the beam firmly, and then pivotallyattaching the clevis back of the bolt, and arranging it to draw upagainst the head and nut of the bolt, the run of the plow as to depth isregulated by raising or lowering the bolt in the slot and securing it inthe desired place.

The letter B represents the handles of the plow, pivotally secured tothe beam by a bolt, substantially as shown; and 0 represents theadjustable stirrup for setting the handles in any desired position as toheight. This stirrup consists of the side bars, (I d, the plates 0 e,and adjustable nuts f and f. The side bars are formed withscrew-threads, which extend upon them for sucli a distance as to reachwell abovethe upper face of the beam, or for such distance as will meetevery exigency of the purpose intended. The side bars are extended andfixed to the handles, substantially as shown. This stirrup being inplace, the operation of adjusting it is simple and well known. It isreadily perceived that its construction and adapt-ability to the purposeadmit of vertical adjustment, and at the same time it maybe movedbackward or forward.

The letter D rep resents the landside, formed to suit the shape of thelower end of the beam, and provided with slotted bolt-holes g g, adaptedto receive the heads of the bolts, which se cure it to the beam for thepurpose of drawing it against the beam. The walls of the slots arebeveled, and the heads of the bolts correspondingly formed, and theslots are so disposed that the landside will follow the form of the beamat these points, and register therewith wherever fixed.

The letter Erepresents a side frame formed withthe raised centralportion, 71, and ends 6, provided with transversely elongated bolt holes00 w, registering with the bolt-holes in the beam, through which thebolts from the landside project, and by which this frame and thelandsidc are secured to the beam. The raised part 72 when the frame isfixed in position, forms, in connection with the face of the beam, aslot or chamber in which the bolts of the shoulder-cuff and mold boardpass, as hereinafter stated. By means of the elongated bolt-holesthisframe maybe adjusted to meet the adjustments of the landside and themoldboard or shovel.

The letter F represents the mold-board, secured in position by a singlebolt, 7., which passes through the mold-board, thence through the slotor chamber between the side frame,E, and the beam, and is. firmly heldby means of the nut on the bolt. means here stated employed to secureand maintain the mold-board in position, it happens that the strain onthe mold-board is such Notwithstanding the I I i i as to twist itsidewise, and thus cause bad work and much trouble. To obviate thisdifficulty and afford ready and sufficient means to secure themold-board in afixed position, I form it with a straight shoulder, m, top rovide a seat for the cuff, now about to be described.

The letter Grepresents abolt,having formed thereon or otherwise providedwith and rigidly secured thereto the head-piece or shouldercuff n,having the under face formed a plane, and in-length equal to the lengthof the shoulder m in the moldboard, upon which it is intended to rest,and the purpose of which contact is that when the bolt is in place, withthe cuff on its seat on the mold-board, the latter is held againstsidewise displacement. This bolt G is provided with screw-threads andscrew-nut on the rear end, and, as shown, passes through the slot orchamber between the side frame, E, and the beam, and is providcd with awasher, c, which washer also serves a like purpose for the bolt 7., andoperates to hold the two bolts accurately in their relative positions.Not only does this cuft'n and bolt serve the purpose, when clamped inplace, to secure the mold-board against twisting or side displacement,but it serves as a means of readily and accurately adjusting themold-board vertically, as well as otherwise, since the mold-board may bethus set in any desired position,and then the cuff being placed on itsseat on the shoulder of the mold-board and screwed tight, it is heldthere against all board or shovel; but such a device is not adapted tobe applied to the plow herein described; and our improvement consistsindis pensing with the grooves on the foot and bolthead and the rabbet,and in forming the bolthead an elongated cuff extending the length ofthe shoulder in the mold-board or shovel.

It is obvious that our improvements are specially adapted to plowsprincipally made of metal, but may be applied to wooden beams with metaladjuncts, and their application to either straight or crooked beams isreadily perceived.

\Vhat we claim as our invention, and desire to secure by Letters Patent,is

1. In combination with the plow-beam, the removable and adjustable sideframe, E, the mold-board secured by the bolt 7:, and the washer o, thebolt G, formed with the head or cull a, substantially as described.

2. In combination, the plow-beam, thelandside, formed with elongatedbolt-holes, and the side frame, E, havingelongated bolt-holes, the saidlandsidc and frame being reinovably and adj ustably secured to the beam,substantially as and for the purpose set forth.

In combination with the beam-handles of a plow, said handles beingpivotally secured to thebeam, the stirrup 0, consisting of the two sidebars, d d, pivotally' attached to the handles, the upper or lower platesor washers c e, and the adjustingquitsff, said plate andadjusting-nuts,with the side bars, being adapted to embrace theplowbeam, substantially as and for the purpose set forth.
